This bronze palace was several hundred meters wide and its surface was covered with green rust. It did not look bright or beautiful at all. Instead, the rust gave off a simple and unadorned feeling.

"Why would there be such a palace in a place like this?"

Of course, it was not like no one in the cultivation world would specially construct a gorgeous palace as their own residence, yet the palace in front of Li Mu was so plain and ordinary, to the point that it could even be said to be dilapidated, to the point that there was even copper rust on it.

Filled with suspicion towards the bronze palace, Li Mu slowly walked towards it. The bronze palace was not far from him, only a hundred meters away.

When Li Mu got closer to the bronze palace, he realized that the bronze doors of the hall were closed, especially the bronze plaque which had three ancient words carved on it — Heaven Burying Hall.

"What big words, he actually dares to use Bury the Heavens as his name. Don't tell me the owner of this palace wants to bury the Heavens, he's simply arrogant!"

When Li Mu saw the three words "Heaven Burying Hall," he immediately muttered in surprise. Although the main entrance to Heaven Burying Hall was closed, Li Mu's curiosity was so strong that he did not plan to leave. This place was strange, so Li Mu wanted to experience what was actually happening inside the Heaven Burying Hall.

The moment he neared the bronze door, Li Mu immediately felt a primordial aura rush towards him. This aura was extremely desolate and heavy, causing Li Mu's mind to become restless.

"Could it be that this was left behind by the ancient Great Desolation Period? This is impossible! Three hundred thousand years have pa.s.sed since the ancient times. This place could not be undiscovered for so many years right? "

The Great Brahma Art in Li Mu's body revolved by itself, and he quickly calmed himself down. He stretched out his right palm, and pushed at the huge bronze door with all his might, but what made Li Mu depressed was, despite his five hundred thousand kilograms of strength, the bronze door did not even open.

After that, he struck out with both palms, using his greatest strength. As he went all out, the huge bronze door finally had a hint of a reaction, and actually trembled a little.

As the huge bronze door was pushed open, an imposing green miasma suddenly surged out of the Great Hall of Everlasting City. In order to push open the huge door, Li Mu had already expended a lot of energy, he never would have thought that after the door was pushed open, there would be green miasma rus.h.i.+ng out, and with a slight misstep, the green miasma washed over the yellow light barrier around him.

"Cough!" Cough cough! "What the h.e.l.l is going on? How dare he sneak attack me?!"

Li Mu, who landed on the ground after being sent flying, had traces of blood flowing out from the corner of his mouth. He coughed a few times before slowly standing up.

Li Mu subconsciously touched the ribs on his left side. He realized that two of them were broken, which made him extremely depressed, but the matter of two broken ribs was nothing for Li Mu, who had reached the sixth form of the Heavenly Demon Nine Transformations.

Li Mu took out a healing pellet and consumed it, after that he gathered his spirit, and continued to walk towards Heaven Burying Hall. At this time, the door to the Heaven Burying Hall was already opened, and there was nothing that could stop Li Mu, as for the green mist that suddenly rushed out of the hall, although Li Mu had not found out what it was up to now, it had shattered the light barrier formed from the destroyed dao qi and broken two of Li Mu's ribs, the green mist had dissipated without a trace.

These bronze coffins were all around the size of a meter and a half long, they were arranged in an orderly manner inside the Heaven Burying Hall, looking very neat. Li Mu scanned them with his Spiritual Sense, and discovered that there were a total of one hundred and eight coffins on both sides of the road, with a special path placed in the middle.

Li Mu quickly calmed himself down from the shock of seeing the coffin, he approached the bronze coffin that was closest to him and attempted to open it with brute force. Li Mu wanted to see what kind of person was inside the coffin, but what made him gloomy was, even under the terrifying force of his Huge Power Qiankun Technique, these coffins that seemed to be made of bronze seemed to be one, and using brute force, was simply unable to open it.

Floating at the center of the altar was a three-legged, seven-meter-tall cauldron. On the altar below the cauldron, there was a one-and-half-meter black hole, from which wisps of green flames would occasionally pour down on the three-legged cauldron, giving the impression that the alchemist was using the earth fire to refine pills. The only difference was that this bronze altar was not an Earth Fire Array Platform, and the four-legged cauldron was not an alchemy furnace.

As for the jade altar, it was placed at the center of the great hall, leaned against the wall and faced the one hundred and eight coffins. On the wall in front of the altar, there was even a painting that was covered in dust, which immediately attracted Li Mu's attention, because he discovered that there were a few items placed on the huge altar.

Li Mu did not immediately touch the jade box on the altar. Instead, he raised his hand and swung it; a cool breeze blew past, blowing all the dust on the wall at the very front of the altar away.

As the dust on the painting disappeared, Li Mu could see the contents of the painting with a glance. This painting was very simple, it only had one person and two lines of words.

The person in the painting was a young man. He wore a dragon robe and had a dragon crown on his head. His left hand was dragging a four-legged bronze cauldron while his right hand was holding a strange weapon that seemed like a blade, but not a sword.

Li Mu's eyes flashed with doubt, and then he looked at the two lines of words on the painting again. Upon seeing the two lines of words, Li Mu could not help but suck in a breath of cold air, the two lines of words were really small, adding together, there were only ten of them.

After Li Mu muttered to himself for a while, his expression suddenly changed. He still vaguely remembered that day in the Dimension of Despair, he heard the Monk Tian Chi mention this name: One Emperor, Two Emperors, Three Empyreans, Four Devil, Five Buddha, Six Demon Saints.

Li Mu carefully recalled the conversation between the Monk of the Heaven Lake Sect and the Blood Cloth Daoist, Jue Tian, and remembered that Monk of the Heaven Lake Sect had said that the Beidou Martial Emperor was from Beidou World. Thinking to this point, Li Mu's eyes couldn't help but reveal an excited look, although he didn't know much about Beidou Martial Emperor, he was definitely an Emperor Level powerhouse, and this Heaven Burying Hall was obviously related to the Beidou Martial Emperor.

When he thought that this Heaven Burying Hall might be related to the Beidou Martial Emperor, Li Mu couldn't help but gulp. He looked at the Bronze Cauldron on the bronze altar, if he wasn't mistaken, this should be a real imperial artefact, and it should be the Beidou Martial Emperor's Emperor Armament.

"Eh …" This is... So familiar, this is... The A Book of Records of the Heavens! "
